Soil acidity and associated aluminium (Al) toxicity severely limit the establishment and growth of legumes in New Zealand high country pastures. A survey of 13 soils differing in location, soil order, parent material and climate, showed soil pH to range from 4.9 to 6.4 and exchangeable Al (0.02M CaCl2) concentrations of
